Ekronite

ek’-ron, ek’-ron-it ’eqron, "migration," "rooting out"; Akkaron:

From the Assyrian records we learn that it revolted against Sennacherib and expelled Padi, the governor he had placed over it, and sent him to Hezekiah, at Jerusalem, for safe keeping. Sennacherib marched against it and Ekron called in the aid of the king of Mutsri, formerly supposed to be Egypt but now regarded by some scholars as a district of Northwestern Arabia. Sennacherib raised the siege of Ekron to defeat this army, which he did at Eltekeh, and then returned and took the city by storm and put to death the leaders of the revolt and carried their adherents into captivity. He then compelled Hezekiah to restore Padi, who was once more made governor. This affair led to the famous attack of Sennacherib on Hezekiah and Jerusalem (Rawl., Anc. Mon., II, 159). Ekron is mentioned in 1 Macc 10:89 as being given by Alexander Balas to Jonathan Maccabeus, and it appears in the accounts of the first Crusade.
